Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum subspecies pallidum. The signs and symptoms of syphilis vary depending in which of the four stages it presents (primary, secondary, latent, and tertiary). The primary stage classically presents with a single chancre (a firm, painless, non-itchy skin ulceration) but there may be multiple sores.
Tertiary stage syphilis can see damage to the brain, heart, eyes, liver, bones, and joints. This damage may be serious enough to cause death. Other symptoms of the tertiary stage include difficulty with muscle movement, numbness, paralysis, progressive blindness, and dementia.
